Previous studies have shown that Egr2 is crucial for normal hindbrain development, peripheral myelination, and humoral immune response and is implicated in diseases such as congenital hypomyelinating neuropathy, Charcot–Marie-Tooth disease, Dejerine–Sottas syndrome, as well as schizophrenia (Boerkoel et al., 2001; De and Turman, 2005; Li et al., 2019; Morita et al., 2016; Okamura et al., 2015; Svaren and Meijer, 2008; Topilko et al., 1994; Warner et al., 1999; Warner et al., 1998; Wilkinson, 1995; Yamada et al., 2007). Here, EGR2 is linked to neuropathy, congenital hypomelinating.
